As mentioned above, all of our drinking water is filtered through two Granulated Activated Carbon filters, as pictured below. We test for Perfluorinated Chemicals before, in-between and after the two filters. If there is a detection in-between, this allows time to change out the one tank well before any Perfluorinated Chemicals creep through the system.

- Our residential water meters have no moving parts. They sense water usage by fluidic oscillation. They are not affected by any tiny particles like other types of mechanical metering devices. They are very accurate, and in the very unlikely event one was not recording accurately, it would most likely be in your favor, and read low.

- If you have high usage and aren't filling a pool or watering your lawn or garden, you may have a leak or even a hose that may have been left on. A 5/8" hose can pass 3,000 gallons an hour.

- Sink and wash tub faucet leaks are easy to see. Toilets may not always be so obvious. If your toilet has a rear tank you can add some food coloring to the water. If the bowl remains clear after several hours, the toilet is fine. A toilet leak can consume up to 2,000 gallons in a day. A silent leak may use 500 to 1,000 gallons/day.

- Check under your crawl space or in your basement weekly - as a leak there can impact more than just your water bill. In addition to water damage, the wetness attracts termites.
